Dude, its gotta be tons more fun flying the Van single pilot below the flight levels than it is flying any sort of heavy iron in the flight levels as a crew.
Every jump seat experience has been 1000 feet autopilot on, shoulder harness off, seat back, Otto to assigned altitude. Then it's 4-5 hours of work work work, schedule schedule schedule......aww...you know they rest......with occasional "Hey did you see the game last night?". I've wanted to shoot myself just sitting in the jump seat (although that might have just been due to riding the jump on a 737, no wonder I have back problems). I ride SWA a ton and it just seems boring to me with very little to do after the FMS is all set up. The rest of the time it's like sharing a IT support cubicle on a weekend shift.....
To a man/woman/wookiee everytime I say I fly the Van most 121 types they get all giddy and talk about how much they miss those days.
(Before you guys jump all up in my grill about the whole don't knock the 121 stuff, I've already started my airline apps application).
